I would definitely start now and not wait until after the next baby. If she becomes pregnant she could add back healthy carbs and gain less extra weight during the pregnancy than she would otherwise.

I don't have an answer for you on the excess skin but I would think it depends on age and genetics. Some people just seem to "tighten up" better than others. Do you ever watch "biggest looser"? There have been quite a few that lost over the 100 lb mark that look pretty tight. I would imagine that if you and your wife are planning another child you are relatively young.

I have low carbed with kids. I just cook basically the same for them but add an additional side dish.

I don't know what you mean by the "net carb craze". I did this diet several years ago and always counted net carbs.

Good luck to you and your wife.
